Question

Explain the causes of biodiversity loss.

Hint:

Preserving biodiversity requires sustainable practices, protecting natural habitats, and mitigating climate change.

Answer 1

Step 1: Human Activities.
Human activities are the primary cause of biodiversity loss. These include:
1. Deforestation: Cutting down forests destroys habitats for many species, leading to a loss of biodiversity.
2. Pollution: Pollution from industrial, agricultural, and urban sources harms ecosystems and can lead to species extinction.
3. Overexploitation: Overhunting, overfishing, and excessive harvesting of natural resources deplete species populations.
4. Climate Change: Human-induced climate change alters habitats, affecting species' ability to survive.
5. Habitat Destruction: Urbanization and agricultural expansion destroy ecosystems that are crucial for biodiversity.
Step 2: Natural Factors.
In addition to human activities, natural factors such as invasive species, diseases, and natural disasters also contribute to biodiversity loss. Invasive species can outcompete native species, leading to their decline.
Step 3: Conclusion.
Biodiversity loss is mainly caused by human activities like deforestation, pollution, overexploitation, and climate change, though natural factors can also play a role.
